I am not yet clear as to why you would not be receiving the email but would like to ask a few questions to try to assist.

Can you confirm the Adobe Ideas version that you are using? What email client you are using? Also, are you sending and receiving other emails from this client? Is the "Ideas" email in your "Sent" folder?

The ability to email your "Ideas" is an important feature and I am hopeful that we will be able to resolve the issue that you are having with the additional information from you.
